In S20, it is determined whether start key 87b has been pressed within a predetermined time. If the start key 87b has been pressed within the predetermined time, the flow shifts to S21. On the other hand, if the start key 87b has not been pressed within the predetermined time, the process returns to S2. That is, until the start key 87b is pressed within a predetermined time, S2 to
The processing of S16 is repeatedly performed.

In step S21, the document presence / absence sensor 27 determines whether the document 21 is placed on the document table 22 of the automatic document reading section (ADF). If the document 21 is not placed on the document table 22 of the automatic document reading section (ADF), it is determined that the document 21 is placed on the document placing plate 31, and the process proceeds to S22 to cut the sheet. It is determined whether the size 56 is stored in the cut sheet size storage area 84b. If the size of the cut sheet 56 is not stored in the cut sheet size storage area 84b, the process proceeds to S2.
3 and the display section 86 displays "Please select the cut sheet size." In S24, the size of the cut sheet 56 is selected by operating the cut sheet selection key 87d by the operator. On the other hand, when the size of the cut sheet 56 is stored in the cut sheet size storage area 84b, the process proceeds to S25.

Is detected by the image sensor 43.

In S27, the image of the document 21 is read, and the number of main scanning lines of the image data obtained by the reading is measured. The number of main scanning lines per unit length, that is, the sub-scanning line density is the standard resolution (standard image quality)
3.85 [lines / mm] for high resolution (high image quality).
7 [books / mm], 15.4 for super high resolution (super high image quality)
[Book / mm]. Accordingly, the length of the document 21 is reduced based on the sub-scanning line density set by the image quality setting key 87e in S2 and the number of main scanning lines of image data obtained by reading while the document sensor 29 is ON. Is detected. Therefore, the size of the document 21 is determined from the width of the document 21 and the length of the document 21 in S26, and R
It is stored in the document size storage area 84a of the AM 84. Then, the image data obtained by the reading is stored in the image memory 85. While the detection signal from the document presence sensor 27 is being output, it is determined that the document 21 is on the document table 22, and the reading operation of the document 21 is repeatedly performed. When the output of the detection signal from the document presence sensor 27 is turned off and the document sensor 29 is turned off, the document 21 currently being read is recognized as the last document 21 and the document 21 is read. Thereafter, the reading operation ends.
